We can speculate but I know a 6 1 G from the 50's would struggle against todays bigger, stronger and faster athletes.

Well, the way I'm looking at it, I am supposing that all of these players are available to draft, right now, in 2007. They're all 21 years old and they all have had the advantages athletes have when growing up in the late 20th century. (Except for steroids. lol)

I think that evens the playing field a bit and lets us consider players from previous era more.

And to your 6'1 argument, Mugsy and Spudd were able to keep up, right?
